Lichen striatus is a type of skin rash. Prominent spots of pink color that join forming red, scaly, linear bands characterize it. It is accompanied by an itching sensation in the affected areas.

The eruption usually appears along with an extremity, following the lines of Blaschko. The rashes affect a more prominent area with time, and it may change the nails sometimes.

It is uncommon and benign, and it mainly occurs in children that are of age 3 to 10, especially females.

The occurrence of this condition is sporadic, and it is even more uncommon in adulthood. However, when it does take place in adults, it is known as acquired blaschkoid dermatitis, or just as blaschkitis.

In this article, lichen striatus will be explained in detail along its symptoms, possible causes, diagnosis, treatment and natural remedies.

Lichen Striatus is a rare and typically harmless skin condition. It commonly affects young children of the age from three to ten. Girls have been more affected by this disorder than boys. It is very rarely found in adults.

In such cases, it is termed as Blaschkitis or Blaschkoid dermatitis, and its appearance is similar to eczema.

The condition is characterized by pink, red or flesh-colored rashes or papules that appear on the skin. They are arranged in a linear band-like pattern and can be found along the limb that is affected.

The name “lichen striatus” originates from the Latin. While “lichen” is defined as a skin disease that produces clusters of small lesions, “striatus” refers to the channel, furrow, or groove appearance.

The disorder affects the extremities, usually one arm or one leg. But sometimes it extends to the neck, torso, buttocks, and abdomen.

It can produce temporary hyper-pigmented or hypo-pigmented marks on the skin even after it has resolved.

Lichen striatus is usually asymptomatic and heals by itself without the need of any treatment. However, when it causes severe itching topical creams are commonly prescribed.  The healing process can also be eased with the use of natural remedies.

What Are Symptoms Of Lichen Striatus:

Lichen striatus is characterized by distinctive pink or flesh-colored lesions in the form of a linear band. They commonly appear on one arm or leg, but they have been found in the neck and trunk too.  Sometimes, they might be slightly hypo-pigmented or hyper-pigmented, that is, a shade lighter or darker than the skin color respectively.

The symptoms of lichen striatus can be enumerated as follows:

  1. Small spots of pink, red or flesh-like colors of 1mm to 3mm in size. Their texture can be either scaly, smooth, or flat-topped. They develop fast and commonly take place on a limb, but they can also extend to the buttocks, abdomen, chest, and neck. These spots or papules form a linear band-like pattern that can be continuous or intermittent. The eruption might last from days to weeks.
  2. Formation of a dull red, scaly linear band after one or two weeks from the appearance of the spots. The band is formed by the joining of these spots. It is 2mm to 2cm in width and a few centimeters in length. It frequently extends over the entire limb length. There might be two or more parallel bands. The band may present hyperpigmentation in light-skinned people and as hypopigmentation in dark-skinned people, making itself prominent on the skin.
  3. Itching (Pruritus) has been reported in several cases. The intensity of this sensation may vary from mild to severe within individuals.
  4. Sometimes the eruption might affect the nails, though it usually affects only one. The affected nail can become thick, longitudinally ridged, brittle, and detached from the nail bed. There might be hyperkeratosis on the nail bed and either thinning, thickening or over-curvature in the nail plate. The nails might be involved at any stage, before or after the development of the rashes on the skin.

Lichen striatus usually affects a limb on only one side of the body. It is known to manifest down the lines of Blaschko.

What Are The Lines Of Blaschko?

These are the lines on the skin that correspond to the pattern of development of epidermal (skin) cells. Their origin is thought to be embryonic. They are invisible under normal conditions, and they can be distinguished only during acquired or inherited diseases that affect the skin.

The pattern of the lines of Blaschko is S-shaped on the abdomen, U-shaped in the upper body, inverted U-shaped on the breast and upper arms, and perpendicular pattern on the lower arms and legs.

The manifestations of Lichen Striatus occur on the lines of Blaschko as papules that form a linear band-like shape.


While the exact reason of this eruption is not determined, the most probable causes are genetic and environmental factors.Lichen striatus is not a contagious or life-threatening disorder.

The possible causes of this condition are:


A family history of asthma, allergic rhinitis, and atopic dermatitis seems to increase the probability of contracting lichen striatus, as seen in at least in 75% of the cases.


Stimuli like infection or trauma can also trigger the onset of lichen striatus. This may include seasonal variations, exposure to UV rays from a tanning bed,pineapple-leaf pricks, and bumble bee bites, though it has not been proven yet.


Sometimes the pregnancy may lead to the eruption of lichen striatus rashes due to its influence in the autoimmune response.


Skin-related diseases like vitiligo and viral infections like varicella and influenza have been found to be associated with lichen striatus. It has also been reported after transplantations of blood stem cells.


In some cases, lichen striatus has been noted after the intake of drugs like adalimumab and etanercept.Immunization with vaccines against Tuberculosis and Hepatitis B can also be followed by lichen striatus eruptions.

Lichen striatusis commonly identified by the appearance of its characteristic rashes in a band-like pattern along a limb involving the lines of Blaschko. Sometimes the nail might be affected by the appearance of these spots.
